It seems like you’ve referenced an undefined Pull Request without providing specific details or context about it. To create a summary for an advanced developer about a Pull Request for the Thanos project, I would typically need information such as:

• The purpose of the Pull Request
• Key changes or additions made
• Any specific files or modules affected
• Related issues or discussions
• Testing or deployment considerations
• Review comments or feedback (if any)

Please provide more details about the Pull Request or describe the changes proposed, and I would be happy to craft a summary!
